FSPN
367User Manual 1179.4363.02 ─ 01
Prerequisites for this command
Turn on XCORR optimization ([SENSe:]SWEep:XOPTimize[:STATe]
on page 366).
Parameters:
<Threshold> <numeric value>
Default unit: dB
Example: //Define a threshold of 15 dB
SWE:XOPT:THR 15
Manual operation: See "Defining cross-correlation parameters" on page 113
[SENSe:]TIME:STARt <Tau>
This command defines the start time for the frequency stability measurements.
Effects of this command
The start time is coupled to the stop frequency offset of the measurement range of
the phase noise measurement ([SENSe:]FREQuency:STOP).
If you change the start time, the R&S FSPN adjusts the stop frequency offset
accordingly. For example, 1 MHz stop offset corresponds to 1 µs.
Parameters:
<Tau> <numeric value>
*RST: 1 ms
Default unit: s
Example: //Define start time for frequency stability measurement
TIME:STAR 1US
Manual operation: See "Defining the measurement range" on page 108
[SENSe:]TIME:STOP <Tau>
This command defines the stop time for the frequency stability measurements.
Effects of this command
The stop time is coupled to the start frequency offset of the measurement range of
the phase noise measurement ([SENSe:]FREQuency:STARt).
If you change the stop time, the R&S FSPN adjusts the start frequency offset
accordingly. For example, 1 mHz start offset corresponds to 1000 s.
Parameters:
<Tau> <numeric value>
*RST: 1 ms
Default unit: s
Example: //Define stop time for frequency stability measurement
TIME:STAR 1000S
Manual operation: See "Defining the measurement range" on page 108
